thanks, lardman, i appreciate the timeliness of your reply. i got and installed X on the Z and it seems to work-i ssh into tincat1(the slackbox) with
"ssh -X -l dp 192.168.1.101" and then "export DISPLAY=192.168.1.101:0"; then, when i attempt an xapp, i get "Xlib: connection to 192.168.1.101 refused by server" and "Xlib: no protocol specified". do i need to enable X-fowarding somewhere as well as authorize the Z to do so, and do i use a display different from the one tincat1 uses or do i use another screen. also to what protocol does the second message refer.
i again thank you for any thoughts you may offer here as i am just trying to muddle through. by the way, what's a good window manager for X on Z?
